The application of CCA BUSBAR in photovoltaic systems offers a number of advantages, especially in the electrical connection of photovoltaic modules and in the transmission of high performance, the following are its main advantages:
Excellent electrical conductivity
Copper has better electrical conductivity than aluminum, and CCA BUSBAR combines the advantages of both. The presence of a tin layer further improves the bond between copper and aluminum, increasing the overall conductivity. The lower resistance of copper-clad aluminum wires compared to pure aluminum wires reduces power losses in photovoltaic systems and ensures efficient current transmission.
Lighter weight
Aluminum has a much lower density than copper, so CCA BUSBAR is lighter than pure copper wire, which reduces the weight of the PV system, especially in large PV arrays, and reduces the cost and difficulty of transportation and installation. This is important for improving the overall efficiency of the PV system.
High corrosion resistance
The tin layer coating provides CCA BUSBAR with excellent corrosion resistance, especially in harsh environments such as humidity, high salinity or acidic environments. The tin layer effectively protects copper and aluminum surfaces from oxidation or corrosion phenomena, extending the service life of PV modules and improving system reliability.
Better soldering performance
CCA BUSBAR has better soldering performance due to the presence of the tin layer. The characteristics of the tin layer make it more weldable, which is conducive to the formation of strong electrical connections in the welding and cable connections between PV cells, ensuring the stability and efficiency of the entire PV system.
Improving the electrical reliability of the system
In PV systems, the reliability of the electrical connection is crucial, CCA BUSBAR’s good conductivity and strong corrosion resistance ensures long-term stable current transmission, effectively preventing electrical failures caused by oxidation, corrosion and other factors. High-quality electrical connections reduce potential electrical failures and ensure efficient operation of the PV system.
Cost reduction
CCA BUSBAR is relatively inexpensive to produce, especially in large-scale applications where the overall cost is more economical than using pure copper tape due to the low cost of aluminum and the protective effect of the tin coating. For photovoltaic projects, this can significantly reduce material costs and improve the system’s price/performance ratio.
Enhanced high temperature resistance
Photovoltaic systems are often located in high temperature environments, especially in hot regions, CCA BUSBAR has good stability at high temperatures, and can continue to maintain good electrical conductivity and mechanical strength in high temperature environments to adapt to the working conditions of photovoltaic systems.
Suitable for high-frequency signal transmission
The working process of photovoltaic module will involve the transmission of some high-frequency signals. Due to the characteristic of “skin effect”, CCA BUSBAR can maintain good performance in high-frequency signal transmission, and its copper layer effectively reduces the loss of high-frequency signal transmission.
Strong environmental adaptability
CCA BUSBAR can maintain stability under different environmental conditions, including UV resistance, humidity resistance and salt spray resistance, etc. It is suitable for use in a variety of environmental conditions, especially in extreme climatic environments such as oceanic climates, deserts, etc., which can improve the overall stability of the photovoltaic system.
Enhanced mechanical strength
Due to the aluminum core, CCA BUSBAR is lighter than pure copper wire, but it still maintains good tensile strength and fatigue resistance due to the tin coating. This is very important for the electrical connections in PV systems, which can effectively resist mechanical stresses and ensure long-term reliable electrical connections.
Summary
The comprehensive properties of CCA BUSBAR make it a highly desirable material choice for photovoltaic systems. Its good electrical conductivity, corrosion resistance, light weight, high transmission efficiency, and low cost make it ideal for use in PV cell series connections, cable connections, and other electrical connections to improve the overall efficiency, stability, and life of the PV system.
